Digital Twin Simulation

The Beer Game

The MIT Beer Game is the world's most widely used supply chain simulation. It demonstrates how rational individual decisions create irrational system behavior (the bullwhip effect) where demand variability amplifies as it moves upstream.

Autonomy includes a full digital implementation with multi-echelon supply chain simulation (Retailer, Wholesaler, Distributor, Factory), supporting 2-8 participants per scenario in real-time via WebSocket.

"The Beer Game has taught more people about supply chain dynamics than any textbook. The bullwhip effect isn't a theoretical curiosity, it destroys value in every supply chain, every day. Simulation is how you see it before it costs you."

Mixed Human-AI Scenarios

The real power is in mixed scenarios. Place your team alongside AI agents to see the difference in real-time:

• Human vs Human, Classic Beer Game for bullwhip education
• Human vs AI, Your team competes against AI agents to see autonomous performance
• Human + AI, Team up with AI agents in mixed roles to build collaboration skills
• AI vs AI, Benchmark different agent strategies against each other

Four Use Cases

1. Employee Training

Scenario-based learning achieves 3-5x higher engagement than traditional supply chain training. New hires experience the bullwhip effect firsthand, understand why autonomous planning matters, and learn to work with AI agents before touching production systems.

2. Agent Validation

Before deploying agents to production, run them through simulation scenarios that stress-test edge cases: demand spikes, supplier disruptions, capacity constraints, quality holds. Verify agent behavior in a risk-free environment with full observability.

3. Confidence Building

Human vs AI competitions demonstrate AI effectiveness in a way that dashboards and reports cannot. When planners see agents consistently outperform them on cost and service level in the simulation, trust in autonomous decisions follows.

4. Continuous Improvement

Human decisions in simulation generate training data for AI agents. Override patterns reveal where human judgment adds value, feeding back into the agent training pipeline for continuous improvement.

"The companies that will lead in the next decade are those that can simulate, test, and validate supply chain decisions before execution. The cost of experimentation in the real world is simply too high."

Digital Twin Training Pipeline

The simulation module serves as the digital twin for the five-phase cold-start pipeline:

1. Individual warm-start, Pre-training from expert curricula
2. Coordinated multi-agent traces, SimPy simulation generates training data
3. Stochastic stress-testing, Monte Carlo scenarios validate robustness
4. Copilot calibration, Human overrides during copilot mode refine agents
5. Autonomous CDC relearning, Production outcomes drive continuous improvement

"The future of supply chain training isn't classrooms, it's simulation. When planners can experience disruptions in a safe environment, they make better decisions under pressure in the real world."
